Automag with RT goes putt-putt...

I rebuilt the valve using a AGD kit (no eBay shiznit!), and while I was waiting for the parts, had Luke set the valve up for a ULT assy. Forward to today: I rebuilt the valve using some of the parts out of the kit (didn't need to rebuild the new ULT). BUT, when I dry fire it.... I get a putt-putt-putt weak sound. It's just meh. I tried a paintball in it, and I probably could have caught it in midair.

SO... I'm not getting the velocity I would expect, even with it turned all the way in... what am I looking for? What did I miss?

That's what I'd heard would happen.... screwed it all the way in, nothing. I've got a new piston coming in, other than that, the only thing that still untouched (save o-rings) is the pin valve and regulator piston springs.

The piston doesn't affect the ability to increase the velocity/air pressure. The piston only affects the safety pressure at which the air will vent if the pressure gets too high. The two springs behind the piston affect the ability to increase the velocity.

Are you using the stock velocity adjuster?

Air rushing down the barrel before properly resetting is usually caused by bolt stick issues. In a level 10, that is caused by having a carrier size that is too tight. Tune your level 10 and use the largest carrier size that doesn't cause any leaking while sitting at rest.

Except for the Automag in front, its usually the man behind the equipment that counts.
